Title: Dry etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/3065
Filed: 1991-06-29
Abstract: PURPOSE:To simultaneously attain to the high anisotropy, rapidity and low pollusion level in the silicon trench etching step. CONSTITUTION:A wafer is cooled down at -30 deg.C to etch away a single crystal silicon substrate 1 using S2Cl2/N2 mixed gas. While Cl* is being etched away in a mechanism assisted by various kinds of ions, a sidewall protective films 5 largely comprising (SN)n is formed by the reaction of liberated S produced from S2Cl2 meeting the discharge dissociation requirements against N produced from N2. At this time, (SN)n in polymer state offering the high resistance to the radical attack or ion shock can attain to the rapidity without deforming the anisotropical shape of a trench 1a even if ionization is accelerated meeting the high bias requirements. Furthermore, the sidewall protective film 5 can be easily and completely decomposed to be removed by heating the wafer at about 100 deg.C so as not to cause the particle pollusion at all.

Accordingly, the active layer 3 is positioned in a buried heterostructure wherein it is blocked up by the n and p type clad layers 2 and 4  above and below, and by a pair of n type buried layers 6 on both sides. Therefore, a threshold current value can be set to be as low as 10-40mA. As the  result, an impressed power is small in relation to an optical output, and the rate of rise in temperature in pn junction is also small.

Title: Control method in case of power failure and device therefor
Inventor: KONO SHINICHI
IPC: G05B19/4063
Filed: 1994-08-08
Abstract: PURPOSE:To prevent the breakage of a tool and a work in case of power failure mode by controlling a tool shaft feeding motor by the regeneration power generated in a motor deceleration mode to evacuate the tool at the time of power interruption. CONSTITUTION:When a power failure occurs in a machining operation state of a numerically controlled gear cutting machine, a power failure detector 20 detects this failure and outputs a power failure detection signal. A power supply regeneration power circuit 18 receives the power failure detection signal and stops an inverter function. Meanwhile a resistance discharge unit 19 is set in an enable state and discharges the extra regeneration power via a resistance. Furthermore a numerical controller 10 gives the commands to an amplifier 13 of a tool motor 16 and an amplifier 14 of a work motor 17 so that both motors are decelerated and stopped synchronously with each other. The controller 10 also instructs an amplifier 12 of a tool shaft feeding motor 15 to evacuate the tool into a safe area. Thus the regeneration power generated by both motors 16 and 17 are returned to a DC link part and used as a driving power supply of the motor 15. Then the tool is kept away from an interference position against a work.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To perform proper work even when the tool axial direction is not vertical to an XY plane by determining an angle between a tool axis directional vector and an axial moving directional vector, and controlling an optimal peripheral speed in this angle so that a cutting speed becomes the same to an optional angle by using this angle.

Abstract: PURPOSE:To prevent the increase of the diffraction loss of light due to a guide groove and to increase the quantity of detection signals, by using the projected part of the guide groove as a track when viewed from the lens side and at the same time setting the track width at >=1/2 track space. CONSTITUTION:An optical disk 1 consists of an optical spot guide layer 5, an information signal recording layer 2 and an adhesive layer 3 formed on a substrate 4 respectively. Then a part where an optical spot stopped down to the layer 2 through a lens 8 against the disk 1 is formed and corresponding to the projected part of a recess/projection area of the layer 5 is used as a track 7 when viewed from the side of the lens 8. Then the information bits 6 are written and read in accordance with the track 7. While the track retrieving signal is produced at a part of the track 7 and the light spot reads out the retrieving signal in accordance with the track 7. The width of the track 7 is set at >=P/2 compared with the track pitch P. This prevents the increase of the diffraction loss due to the layer 5 and can increase the quantity of detection signals.
